IMPROVEMENT IN CONDUCTORS lN MACHINES FOR FORMING HAT-BODIES.

Specification forming part of Letters Pate-nt N0. 9,970, dated August 30, 1853.

.To all whom it may concern:

Beit known that I, LANSING E. HOPKINS, of New York, in the county of New York `and State of New York, have invented a certain new and useful Improvement in Manufacturing Hats; and I do hereby declare that the following is a full, clear, and exact description of the principle` or character whichdistinguishes it from all other things before known, and of theV usual manner of making, modifying, and using the same.

Myimprovement in forming hat-bodies consists in a bifurcated conductor so constructed and arranged as to place the exhaust-cone between two jets of fur.

The construction of that part of the machine by which this new effect is produced consists 0f two tubes of curved form uniting in one at the picker, which is of ordinary construction and not shown in the drawing. Its place is at c. From thence the tubes run a short distance parallel, having but asingle partition, b, between them. They then branch outward with a gentle curve, and their cross-section gradually narrows in breadth and increases in height, their extreme ends curving inward till their openings are opposite each other. Be-

tween these openings stands the cone c, upon which the hat-bodies are formed. On either side of the tubes, near their extreme ends, are sliding shutters, that can be made to slide forward, and by so doing in some degree close the openin g. By regulating these shutters on one or the other', or both, produce the effect above named of strengthening thebody in any desired part. 1 effect this by the double outletwit-h more accuracy than could be done in any othervway, throwing the fur upon the cone in more than one point.

Havingthus fully described myiinprovement in hat-forming machinery, whatl claim therein as new, and for which l desire to secure Letters Patent, is

The bifurcated conductor and blast above described, said conductor having its` openings opposite each other, or nearly so, and Vhaving the cone between them, substantially in the manner and for the purpose set forth.
